No. 1 Given are the vertices ∆ABC: A (6; –9); In (10; –1); C (–4; 1). Find: a) The equation of the side AB; b) Equation of height CH; c) the equation of the median AM; d) the point N of the intersection of the median AM and the height of CH; d) the equation of a line passing through the vertex C and parallel to the side AB; e) the distance from point C to line AB.

№2 Make an equation of the height drawn through the vertex A of triangle ABC, knowing the equations of its sides. AB: 2x - y - 3 = 0; AC: x + 5y - 7 = 0; BC: 3x - 2y + 13 = 0.
